| pondering whether human engineers can't put these | | | | wings themselves as part of the fuel. Meaning, the |
| same mechanical concepts to use in the construction | | | | wing would ideally be constructed of a poly plastic |
| of their aircraft machines. One idea worth testing is | | | | that can be converted into engine power at the |
| the incorporation of materials with memory into | | | | melting point. In essence, the wings dissolve upon |

| to normal position when bent. Relative water flows, | | | | running on guts, body fat and sheer will power.As the |
| created current from AUV, or increased back | | | | aircraft eats the inside of the wing which is made of |
| pressure from forward momentum against the | | | | a poly type plastic, it is dissolved, thus the aircraft |
| artificial fin or wing, would force it back to its position. | | | | converts this into energy and the weight is |

| lightness of the machine, the force by which it | | | | goal line to win a victory point in the overall battle; |
| propels itself, and the density of the wing structure | | | | thus, scoring points against the opponent.The reason |
| must all be taken into account. The "flying or | | | | we use the wing is that it can be hollow and it is at |

| Air/Water Crafts and Energy-Efficiency:In our | | | | check, unless a downward angle of attack and |
| hypothetical memory-material model, the propulsion | | | | proper speed was continuous. One variation on this |

| and therefore less controlling surfaces, less | | | | momentum and thrust. Since the chief purpose would |
